چکیده
مقدمه

فعالیت بدنی مهمترین عامل مصرف انرژی در انسان است. انرژی دریافتی می­‌تواند بیان ژنی آدیپونکتین را به طور مثبت یا منفی تنظیم کند. از این­‌رو، ممکن است تغییر در مصرف انرژی از طریق تمرین ورزشی نیز بر میزان آدیپونکتین تاثیرگذار باشد. بنابراین، پژوهش حاضر با هدف بررسی تاثیر 8 هفته تمرین مقاومتی بر سطح آدیپونکتین، مقاومت و حساسیت انسولینی و هموگلوبین گلیکوزیله در مردان دارای اضافه وزن انجام شد.

مواد و روش‌­ها

در این مطالعه نیمه تجربی، تعداد 22 مرد دارای اضافه وزن (0/96±28/76= شاخص توده بدنی و 2/23±31/31= سن) انتخاب و به صورت تصادفی در دو گروه تمرین مقاومتی (11نفر) و گروه شاهد (11نفر) قرار گرفتند. تمرین مقاومتی با شدت 55-75 درصد یک تکرار بیشینه، 8 هفته و 3 جلسه در هفته انجام شد. نمونه خونی آزمودنی‌­ها برای اندازه‌گیری سطوح آدیپونکتین، انسولین و گلوکز خون به صورت ناشتا، 24 ساعت قبل از شروع و 48 ساعت پس از آخرین جلسه تمرینی اخذ شد. داده‌­ها با استفاده از آزمون آماری آنالیز واریانس یک­‌راهه تحلیل شدند.

یافته‌­ها

تمرین مقاومتی باعث کاهش معنی­‌دار وزن (0/05>P)، شاخص توده بدن (0/05>P)، انسولین (=0/001P=)، مقاومت انسولین (0/004P=) و افزایش آدیپونکتین (0/001>P)­ و حساسیت انسولینی (0/025P=) شد. اما تغییرات سطح گلوکز خون (0/201P=) و هموگلوبین گلوکوزیله (0/686P=) از نظر آماری معنی­‌دار نبود.

نتیجه‌­گیری

با توجه به اثرات مطلوب تمرین مقاومتی بر سطح آدیپونکتین و ترکیب بدن به نظر می­‌رسد، مشارکت در این نوع تمرینات می‌­تواند باعث بهبود حساسیت انسولینی و کاهش اضافه وزن شده و فاکتور مهمی در کنترل و جلوگیری از ایجاد بیماری­‌های مرتبط با افزایش وزن باشد

چکیده English

Introduction

Physical activity is the most important factors of energy consumption in humans. Since energy absorption can regulated the adiponectin expression positively or negatively. Also, altering energy consumption with exercise may affect the adiponectin levels. Therefore, the present study aimed to the effect of 8 weeks resistance training on adiponectin, insulin hemostasis and HbA1c levels in overweight men.

Materials & Methods

In this semi-experimental study, total of 22 overweight young healthy men (BMI 28.76±0.96 and age 31.31±2.23) were randomly assigned to control (n=11) and resistance exercise (n=11) groups. Subjects in the resistance exercise groups participated on 8-week exercise training programme with 55-75% of 1RM for three sessions per week. Anthropometric indices (weight, body fat percentage, BMI) were analyzed. Insulin, glucose, adiponectin, HbA1c and HOMA-IR were assessed from fasting blood samples before and after the 8-week exercise programme. Data were analyzed by t-test.

Results

Resistance training led to decrease in Anthropometric indices (P<0.05), insulin levels (P=0.001) and HOMA-IR (P=0.004) and increase adiponectin (P<0.001) and QUICKI (P=0.025). But changes in glucose (P=0.201) and HbA1c (P=0.686) levels was not significant.

Conclusion

Considering to the effects of resistance exercise on Adiponectin levels and body composition, it seems that participation in this type of exercise, can improve insulin sensitivity and weight reduce, also an important factor in controlling and preventing the overweight-related diseases.
